Principle:: an Architecturally visible unit of data can only become
visible after the causing instruction retires. A high precision timer
makes cache line [dis]placement visible; so either take away the HPT
or don't alter cache visible state too early.

And parallelism (e.g. multicores) can be used to emulate HPT, so "take
away the HPT" is not really an option.
